all wliomyt may concern: lie it known that l An'rnuic JAMES AN Wilson, ucitizen of the United t-Stutes, resid 111, nt Blots-rd, in the county oi(iriggs und State of North Dakota, have invented ccrtuin new and usefulImprovements in. l.)e i'nountehle Rims for l /lotonVehlclcs, of whichthe following is e specification, rol erence being had therein to theeccompnnying drawings.

This invention relates to e demourituhle rim forthe wheels of motorvehicles, on which wheels are preferably mounted. pneumatictires.

The object of the invention is the provi-v sion of simple and ellicient,means for quickly and eiliciently permitting the removal of the a wheel,end quickly and elliciently allowing the rim, when. placed upon thewheel, to be securely fastened thereon With this and other objects inview, my invention'consists of certain novel. construe tions,combinations, and arrangements of hereinafter fully described andclaimed. i

In the drawings,

Figure 1 is a view in side elevation of u wheel equipped with myimproved mechanism, portions of the telly plate being broken away to,show the interior structure of the mechanism.

Fig. 2 is a, view in side elevation of the folly of a, wheelconstructed'in accordance with the present invention, showing the ,1.plate broken away showing the auxiliary hearing plate in elevation.

Fig. 3 is an edge view, in elevation, of the rotatable driving ring.

Fig. 4: is e transverse sectional view taken on line 4- Fig. 1, lookingin the direction of the arrows. 1 i

' Fig. 5 is: an enlarged sectional view taken on li'he 5-5,.,,Fig.'1.

Fig. 6 is e fragmentary view, in side elevation, of the folly showingthe pivoted coverplate.

Fig. l is n holts, While Fig. 8 is a, perspective view normally carriedby each bolt.

Fig. 9 is a view similar to Fig. 5, of another GlllbOClllllBlll, of thepresent invention.

Referring ers ective view of one of the i p of the pinion to thedrawings by numerals, in the construction of my improved mochm lli'SIlflfor quickly attaching end detaching a rim, I employ a telly 1 mountedupon spokes Specification of Letters Patent.

2 end huh 23. The folly l is provided with u dctuclmhle rim l of anydesired construction for receiving it tire, the rim i beingpro videdwith an inner, inclined face 5 that rides upon thesinrilurly-constructed outer iuce (3 of the folly 1. (Fig. 5). When therun -l is forced upon. the telly 1 end wedged" thereon by reason of theinclined, engaging faces 3 mid -11, there will he required locking bolts7 (entering sockets 8 kit their upper ends) to securely retain thedctnchublc rim 4; upon t'clly 1.

Tlhe locking bolts 7 nrc threaded lain. 5),

und these bolts puss through angle plates 9,

which plates are detuchuhly secured, by screws 10, in the sockets ll, inwhich sockets 11 are also positioned the pinions 12, which pinions 12are tlnrcudcd upon the of the bolts 7, so that when rotury movement isimported to pin ions 12, bolts 7 will be rotated for adjusting the sumowith respect to sockets 8 in the rim 4. Each bolt 7 is pl ovir ,d withon integral, reduced, squared extension l t at its inner end, whichsquared extension 13 is slidubly mounted. in o squared socket 14 thatopens into the larger socket 15 in which the threaded end of bolt 7 isslidebly mounted; this squared extension 13 prevents the bolt fromhavingany rotury movement, thercby making its movement more positive,since pinion 12, when rotated, will quickly ectu ate the bolt fornursing it with respect to the rim l.

Cut in one side of the folly 1 is an a nulor groove 16, inwhich isloosely mounted the driving ring 17. The ring 17 is held in groove 16 bythe annular plate 18, which plate 18 is fastened toithc side of thefolly by means of screws 19.

The driving ring 17 is provided with teeth 20 formed on one edge 0'[ thesmile, and these teeth 20 mesh with the teeth of pin ion 12, so thatwhen the ring 17 is rotated, pinion 12 will be rotated for actuating thebolts 7, with reference to causing the some to positively lock the ri n14: upon the telly, or releese the rim so that it may be reu'ioved offthe folly with the tire that may be carried thereon. The driving ring17-has teeth 21 formed upon its inner face, and teeth 21 mesh withdriving pinion 22. pinion is journulechnt its outer end 23, in auxiliaryplate 24, end the inner, squared end 25 is positioned in the key socket526, the

This driving;

of the key socket 26 being; closed the driving ring 17 for rotating" thepinions 12 mounted upon the locking bolts 7.

At the inner end of the key socket or pocket 26 is a bearing plate 29,through which the squared end 25 of pinion 22 projects; this plate 29,as well as the auxiliary plate 24. constitutes an efficient bearing forpinion 22.

From the foregoing description, it will be understood that to locktherim upon the telly, it will be necessary to first slide or force rim atupon the inclined face dot the telly, until the rim is fully upon thetelly, as shown in Fig. 5, and then by operating the key 28 upon thesquared end of pinion 22, the driving ring 17 will be rotated, impartingrotary movement to all the pinions 12 ot' the bolt devices, causing theseveral. locking bolts 7 to move into engagement with rim 4, by reasonof the upper or outer ends of the bolts being seated in the sockets 8.To release therim 4, all that the operator has to do is to rotate thepinion 22 in the reverse direction, through the medium of the tool 28,causing the-bolts 7 to move downwardly or inwardly toward the hub asutlicieut distance to move entirely out of the sockets 8 when the rimwill be unlocked, per mitting the operator toquickly remove the rim(usually carrying a pneumatic tire 30, Fig. 1) from the telly for anydesired'purpose. It will be obvious that any number of bolt-devices,actuatedby the driving ring 17, can be placed upon a wheel constructedin accordance with the present invention, as the number of these devicesis entirely 0ptional with the constructor or manufacturer of the wheeland its cooperating parts.

In Fig.9, I have shown an embodiment of this invention in which all ofthe parts are similar'except bolt 7 in this type of a boltt'asteningdevice, the bolt 7 is not provided with a squared extension at its"inner end,'but is elongated so that there is a I smooth portion 7 atits inner end, the threads on the bolt being intermediate its ends, uponwhich threads or threaded portions of the. bolt, pinion 12 is mounted.

I reserve the right to make such alterations and modifi -ations andchanges as shall appear to one skilled in the art to which thisinvention relates, which alterations, modifications, or changes shall befound necessaryin the manufacture of my invention, and which shallfairly fall within the scope of the appended claims. i

What I claim is;

1. In a mechanism of the class described, the combination with a telly,of a detachable rim mounted upon said telly, a plurality of lockingbolts slid-ably mounted upon the telly and being adapted to engage saidrim, pinions rotatably mounted upon said bolts, a rotatable driving ringmeshing with said pinions and adapted to be rotated itor driving thepinions for actuating-the bolts to move the same to a locked or unlockedposition, and means for rotating said ring.

2. In a mechanism of the class described, the combination with a tellyprovided with an outer, beveled face, of a detachable rim provided withan inner, beveled 'l ace engaging the outer face of said telly, said rimprovided on its inner face with a plurality of sockets, said follyprovided with sockets registering with the sockets of said rim. boltsslidably mounted in the sockets of the folly and adapted to enter attheir outer ends thesockets in the rim. angle plates dctachabl y securedwithin said telly said bolts extcnding through said plates, pinionsthreaded upon said bolts parallel to a portion of said plates, saidtelly provided in one face with a collar groove. said pinions extendinginto a portion, of said groove, a driving ring,- in said annular groove,said ring provided on its edge and on its inner r'ace'with teeth, theteeth. on the edge of the ring meshing with the teeth on the piuions, adriving pinion provided with a squared. outer portion and an innerextension meshing with the teeth on the inner face of the ring, saidtelly pro ivided with an. auxiliary plate in which the inner extensionand the driving pinion are journaled, the squared end of the drivingpinion extending into a socket fornuid. in said folly, a plate at theinner end. of said last-mentioned socket and supporting the squared endof said pinion, and a pivotallymounted cap closing the outer end of saidlast-mentioned socket.

In testimony whereof I hereunto aflix my signature.
